MUSIC-LEAF HOLDER AND CLAMP.

To all whom it may concern:

Be it known that I, O'r'ro B. WVILLI, citizen of the United States,residing at Youngstown, in the county of Mahoning and State of Ohio,have invented certain new and useful Improvements in Music-Leaf Holdersand Clamps, of which the following is a specification.

This invention relates to music holders and clamps especially adapted tobe used in conjunction with keyboard instruments and upon music stands,and has for its object to provide holding mechanism which may be easilyand readily adjusted to be ac commodated to sheets or books of difierentsizes and which may be quickly and easily manipulated or operated toeffect the turning of the leaves.

The present invention is an improvement in the structure shown in myearlier application forpatent for music leaf turner, filed March 11,1910, Serial No. 548,691.

The parts of the present invention are so arranged that they may beapplied to the panel and music shelf of an instrument case or to a musicstand without altering or mutilating the same to any considerableextent, and provision is made for concealing the major portions of theparts behind the panel or stand when the holder is not in use.

In the accompanying drawings:Figure 1 is a perspective view showing theholder and clamp applied to the panel and shelf of the case of a piano;Fig. 2 is a transverse sectional View through the panel showing theholder and clamp applied; Fig. 3 is a horizontal section through thepanel showing the holder and clamp applied; Fig. 4 is a horizontalsectional view of a clamp used in the device; and Figs. 5, 6, and 7,detail views of modified parts of the device.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

As indicated in the drawings, 1 represents the hinged panel of the caseof the instrument which is provided at its lower edge with the usualmusic shelf 2.

3 indicates that portion of the case which Specification of LettersPatent.

is located just above the key bank 4 of the instrument.

A cylinder or body 5 is fixed to the rear side of the panel 1 andcontains the mechanism for swinging the arms, hereinafter to bedescribed, and this mechanism is operated by levers 6 which projectthrough the portion 3 of the case of the instrument and are located justabove the key bank 1'. The mechanism located within the cylinder 5 forswinging the arms may be the same as that shown and described inconnection with the mechanism illustrated in my earlier applicationhereinbefore referred to, and as this mechanism forms no part of thepresent invention, description of the same is unnecessary in the presentinstance. Su'lfice it to say that the arms 7 are pivot-ally mounted attheir inner ends within the cylinder or body 5 and are adapted to swingin planes at right angles to the long dimension of the said cylinder orbody 5. The arms 7 carry at their outer ends leaf holders 8 which are ofespecial design and construction, as will now be described. Theseholders consist each of two opposed thin strips of metal which areprovided at their edges with diverging flanges 9. The side portions ofthe holders 8 may be formed by bending a single strip back upon itselfor may be composed of two independent strips secured at their lower endsto the arms 7. When the levers 6 are depressed the arms 7 and theirattachments are swung successively by the mechanism hereinbeforereferred to located in the cylinder or body 5 and which is not shown.The upper ends of the holders 8 are enlarged forming heads 10.

The panel 1 is provided at its lower edge with a. vertically disposedslot 11, best seen in Fig. 1 of the drawings, which is provided at itsupper end with an enlargement 12. At its lower end the slot 11 entersthe rear end of an arcuate slot 13 provided in the shelf 2. These slots11 and 13 are located at one side of the cylinder or body 5, and at theopposite side of the said cylinder or body the shelf 2 is provided withan arcuate slot 14 which is located the same distance from the saidcylinder or body as the slot 13.

A rod 16 is slidably mounted in the shelf 2 and is provided at its outerend with a knob 17 which normally bears against the outer edge of theshelf 2. At its inner end the rod 16 is provided with an angularextremity 18 which extends transversely across and behind the innermostarm 7 The body portions of the arms 7 are at the same elevation and arearranged one behind the other. Therefore it will be seen that when therod 16 is moved forward by a performer pulling the knob 1'? theextremity 18 of the said rod 16 will engage the innermost arm '7 andmove the free end thereof together with all of the other arms 7 outthrough the slot 11 beyond the forward surface of the panel 1. Thus theholders 8 are brought to accessible positions and the performer mayplace the leaves of a book or sheet music between the side strips ofeach holder.

Clamping mechanism is provided for holding that portion of the musicwhich is not to be used in close relation to the panel. As illustratedin Figs. 1, 2, 3 and 4: this clamping mechanism consists of sleeves 1and 20 which are inserted in the lower edge of the panel 1 and the outeredge of the shelf 2 respectively. A tube 21 is slidably mounted in thesleeve 19 and carries at its outer end a resilient finger 22. The tube21 provided at its inner end with an enlarged head 23 which is providedat its rear side with a diametrically disposed recess 24. A coil spring25 is interposed between the inner end of the sleeve 19 and the head 23and is under tension with a tendency to hold the finger 22 toward theouter surface of the panel 1. A rod 26 is slidably mounted in the tube21 and is provided at its outer end with a knob 27 which normally bearsagainst the outer end of the sleeve 20 and limits the inward movement ofthe said rod 26 and the tube 21. At its inner end the rod 26 is providedwith a cross head 28 which at times is adapted to seat in the slot 24:provided in the head 23, whereby the rod 26 may be used as means forturning or partially rotating the tube 21 and its attachments. The shelf2 is slotted as at 29 to receive the outer portion of the rod 26 andalong which the lower end of the finger 22 and the outer end of the tube21 may pass. From the outer end of the slot 29 the shelf 2 is slotted asat 30, the slot 30 extending generally at a right angle to the longdimension of the slot 29, and is adapted to receive the finger 2 whenthe same is pulled toward the outer edge of the shelf 2 and is swung ina downward direction. The slot 30 is provided at that end remote fromthe slot 29 with a ledge 31 upon which the free end of the finger 22 mayrest and which limits the downward swinging movement of the said freeedge of the finger with relation to the shelf 2. hen the finger 22 isreceived within the slot 30 the tube 21 and its attachments are held inoutward positions against the tension of the spring 25. The clampingdevice as above described is duplicated, one device being located ateach side of the cylinder or body 5.

The clamping devices, as has been hereinbefore stated, are designed tohold the pertions of the music which are not to be used in closeproximity to the outer face of the panel, and in positioning the musicupon the panel it is opened and the portions not to be used are placedbetween the panel and the fingers 22 and the springs 25 hold the saidfingers against the said portions of the score, while the leaves whichare to be used are positioned in the holders 8, as hereinbeforedescribed. Thus the leaves of music may be turned at will, and when theholders 8 leave the slot 13 in the shelf 2 they swing across into theslot 141- in the said shelf. There they may remain until they are swungback by the performer.

In the form of clamp as illustrated in Figs. 5 and 6, the coil spring 25is dispensed with and two springs are employed. One of these springs 32is attached at one end to the back of the panel 1 and at its other endis connected with one end of the rod 26 and is under tension with atendency to hold the knob 27 toward the edge of the shelf 2. The otherspring 33 is attached at one end to the back of the panel 1 and at itsother end bears against the forward face of the head 23 and is undertension with a tendency to hold the tube 21 within the panel 1 and thefinger 22 carried thereby toward the outer face of the said panel. Thisform of clamp is manipulated in the same manner as that described inconnection with the form shown in Figs. 1, 2 and 3 of the drawings.

In the form of clamp as illustrated in Fig. 7, but a single spring isemployed, this spring being indicated at S t and has one of its endsattached to the shelf 2 and its other end bearing against the head 23 ofthe tube 21. In this instance the tube 21 is much shorter than the tubesshown and described in connection with the clamping devices illustratedin Figs. 1 to 6, inclusive, and therefore the parts do not project toany considerable extent behind the panel 1.

Having thus described the invention, what is claimed as new is:
